Potential Applications of Steel Fin Piles in Highway Transportation Infrastructure

Steel fin pile foundations utilize fins on the side of the piles to develop significant frictional resistance between the soil and the finned pile. The fins serve the purpose of increasing lateral and torsional resistance of the pile. Typical scenarios with large lateral and torsional loads can be found in foundations for power transmission lines, roadway signage, solar panels, wind turbines, and marine applications. Many of these loading scenarios are common in highway transportation projects. Steel fin pile foundations are a rather new product to the market and case history data of applications and performance are limited compared to conventional alternatives such as shallow foundations, driven piles, and drilled shafts. The goal of this study is to provide a comparison for steel fin pile foundations with conventional alternatives. Additionally, field load testing of steel fin pile foundations was performed at an existing project site to evaluate engineering performance. This study will focus on ease of construction, applicability for different transportation infrastructure, and cost. The results of the load test data and comparison with conventional design show the viability and economy of steel fin pile foundation use in highway transportation projects.
